on browser reload/refresh/close alert and then ajax

Question

Is it possible to fire an alert on browser close? If user confirm "reload/close" then want to execute some ajax stuff. This is I have tried so far

window.onbeforeunload = function () {
    return 'This will close your chat session. Are you Sure!';
    var meta_id = $('#meta_id').val();
    $.ajax({
        url: site_url + '/chat/send_offline',
        type: 'post',
        cache: false,
        async: false,
        data: {
            meta_id: meta_id
        }
    });
}

As far I know code not execute after the return statement. So is it possible to alert and execute ajax code simultaneously if user confirm??

@Justinas In `onbeforeunload` event `confirm()` or `alert()` doesn't work — Rejoanul Alam, Sep 10 '15 at 06:25
Actually some web apps have “Do you want to close this window” error at running forms,or doing http calls . I think you can search how can you activate it — hurricane, Sep 10 '15 at 06:38

I found this in MDN documentation

window.addEventListener("beforeunload", function (e) {
  var confirmationMessage = "Do you want to leave this page ?";

  // Call AJAX RIGHT HERE

  e.returnValue = confirmationMessage;     // Gecko and Trident
  return confirmationMessage;              // Gecko and WebKit
});

You have to call the Ajax before return in the function. Because return break the execution of the function.

This will not solve the issue because if user close browser and alert message shown after ajax call then all action will be wrong (if user cancel the browser close) – Rejoanul Alam Sep 10 '15 at 07:04
It seems that is not possible to catch the anwser of the user. [link](http://stackoverflow.com/a/5400059/4547547) But you can use the unload event to make your Ajax call ! https://developer.mozilla.org/en-US/docs/Web/Events/unload – I'm_ADR Sep 10 '15 at 07:14

Maybe chrome.runtime.onSuspend or chrome.windows.onRemoved will help you?
